He also takes up Amanzta, and uses it for the first time in the 
modern sense as including species with an evident basal volva. 
His type, however, would fall among the ex-annulate species 
now usually included in Amanztopsis. In Synopses Methodica 
Frungorum (1801) he reduces all of these except Amanita 
to sections of Agaricus. For his sections he also uses a number 
of other names which were taken up by Fries and hence have 
come down to us as generic names as used by Saccardo and 
other modern writers. In many cases, however, these modern 
genera do not contain what would have to be considered as 
Persoon’s types had he given his groups generic rank. 
In 1806, Roussel, in the admirable little work already cited, 
raised many of Persoon’s sectional names to generic rank. It 
seems remarkable that this important work has been so com- 
pletely overlooked. It is rarely cited and even seems to have 
escaped the keen eyes of Otto Kuntze, yet we get from it the 
earliest generic use of at least eight names for the gill fungi 
and of very many more inthe other groups, including such 
important ones as Albugo and Ustilago. Here too, on page 
59, we find Amanitoideae used as a family name for the gill 
fungi, the earliest family name to be applied to them. 
S. F. Gray (1821) is the next important author from the 
generic standpoint. Eight of his names may be found in the 
available list. They include Lepzota and Crepidotus. The 
latter, however, is not used for brown-spored species as it was 
by Fries but the well-known Pleurotus ostreatus must stand 
as its type. 
For the sixty years (1815-1874), during which Elias Fries 
was publishing on the gill fungi, he consistently followed 
Persoon in keeping the great majority of species in the single 
genus Agaricus, which he divided into numerous subgenera 
or, as he called them, ‘‘tribes.” At one time or another, 
however, mostly in Genera Hymenomycetes, a pamphlet 
published in 1836, he established seventeen genera, a number 
of which he later reduced to subgeneric rank.
